Answer:
2I- ---> I2 + 2e- = O
Au+3 + 3e- ---> Au = R
Explanation:
The first loses electrons, so it is Oxidized, and the second one gains electrons, so it is Reduced. (Also I just did this and saw the answers were O and R respectively)
Answer:
c. 1.4 x 10²³ oxygen atoms
Explanation:
The number of oxygen atoms in one molecule of CH₃COOH is 2.
Avogadro's constant relates the number of molecules in one mole:
6.022 × 10²³ mol⁻¹
Thus, the number of oxygen atoms in one molecule of acetic acid can be converted to the number of oxygen atoms in one mole of acetic acid:
(2 oxygen atoms / molecule)(6.022 × 10²³ molecule / mol) = 1.204 x 10²⁴ atoms per mole
Finally, the number of oxygen atoms in 0.12 moles of acetic acid are calculated:
(1.204 x 10²⁴ atoms / mol)(0.12 mol) = 1.4 x 10²³ atoms/mol
Answer:
0.67 cm³
Explanation:
We can solve this problem by using the <em>definition of density</em>:
We can rearrange the equation and isolate volume:
As we are given both <em>the mass and the density</em>, we can now<u> calculate the volume</u>:
- Volume = 13 g ÷ 19.3 g/cm³
Answer:
visible light falls between which set of waves within the electromagnetic spectrum?
D.) infrared and Ultraviolet
Answer:
Explanation:
From the information above:
The equation for the reactor volume of CSTR is given by the formula:
The reaction rate of A is:
and k = 3 dm³/mol.h
replacing the values in the above equation to solve for v;
∴
V = 66,000 dm³
Thus, the reactor volume of CSTR is 66000 dm³
Taking the differential mole balance equation for PFR is as follows:
Taking the integral between initial and final concentrations;
replace the values in the above equation;
Thus, the reactor volume of PFR is 660 dm³
